Change the default stack size to 8 MiB for 64-bit and 0.5 MiB for 32-bit. CEF's main thread needs at least a 1.5 MiB stack size in order to avoid stack overflow crashes. However, if this is set in the PE file then other threads get this size as well, leading to address-space exhaustion in 32-bit CEF. A new CefRunWinMainWithPreferredStackSize function uses fibers to switch the main thread to a 4 MiB stack (roughly the same effective size as the 64-bit build's 8 MiB stack) before running any other code. This change additionally moves the existing Windows-only functions CefSetOSModalLoop and CefEnableHighDPISupport from cef_app.h to cef_win.h.
